If you still get process killed during heavy swapout (cause OOM of
an ATOMIC allocation) please try to increase the ATOMIC pool before
designing a separate pool. We just have a pool for atomic allocation
it may not be large enough for the increased pressure on the regular pages.

        echo 1000 2000 4000 >/proc/sys/vm/freepages

This way you'll basically waste 16mbyte of ram.  It's just to check if
the ATOMIC allocation shortage is the source of the segfault or not.
